Molecule consists of a molecular structure editing phenol hydroxyls directly connected to the benzene ring. According benzene Kekule formula, the hydroxyl groups are attached to the double bond of the enol structure. However, due to the stability of the benzene ring of phenol quotes, such a structure is hardly converted to the keto form. Phenol resonance structure as above right. An oxygen atom of a phenolic hydroxyl group using sp hybridization, provides one to six carbon atoms with lone electron delocalized phenyl ring together form a bond. Large π bond strengthened alcohol acidic phenol, pushing electronic effects also strengthened polar hydroxyl OH bond factory direct sales of phenol, phenol hydroxyl hydrogen and therefore can be ionized out. Phenolate anion resonance structure is like below right: Factors schematic editor heat of vaporization temperature and pressure vaporization heat and vaporize when relevant. Vaporization heat is reduced when the temperature rises, becomes zero at the critical temperature. This is because as the temperature rises, the liquid will have a larger molecular kinetic energy, the difference between gas and liquid phases is gradually decreased, the liquid from the outside simply obtained less energy vaporized. And at the critical temperature, the material differences in the critical state, between the gas phase and liquid phase disappears, so the heat of vaporization is 0.
